I'm getting a decent amount of unsolicited messages, latest example:
[thwack] Announcement: Join us TODAY for thwackCamp Holiday thwackTacular 2014 @ 9AM - 3PM CST
[thwack] Announcement: TODAY @ 1PM CT SolarWinds Lab #20: Monitor Active Directory (AD) Events
The issue is this email does not have an unsubscribe button, which I believes violates the CAN-SPAM Act? How can I unsubscribe from these emails?
